Lonnie "'lt'JllGJly in a device for converting fuel oil it highly inflammable spray and ejc 'ng 1 Y in a manner that will ited for producing a flame the nhjects oi the inventionis to pro. anoil :urueroi? this character couetrnctecl to receive oil super-heated steam, end end to properly cause the said ele ments to interniingle whereby an. inflzun mabic spr may he produced for the pur- 'iding a jet of flame having an extren intense heat.

a further object of the invention,- the device inv dcs the provision of a mixing chamber inecied with a suitable supply I gncd to convey both steam and oil ii'ito the mixing chamber whereby'an atone ized liquid, no he formed for; being ejected from the on n nor in the form of a tubular swirlin Y micron. 7

object or the invention is the a di ci irrgc tube for conveying iiuinn of infi amicable spray out "in of a jethaving consider n J a ciated with an air outlet pc to prevent e formation of carbon wi hin. the outlet pipes when the device is in operation The invt-zntion also includes the provision oi? means or permitting the operator to observe ti' fie whereby it may be properly regula through suitable adjusting means provided r th s purpose.

A further obiect oi this invention is the provi ion or on oil burner which consists of con'ipzi.

naively few parts and is sim le in construction, but durable and well a apted to Withst id thorough usage to which de vices of this character are ordinarily subjected.

For a fuli description of the invention and the advantages and merits, thereof refe'ence is to be had to the following description and the accompanying drawings.

wherein is illustrated the preferred forth of my invention, .111 which;

Figure 1 is a side elevation showin my invention applied to the front of a boi er.

Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1.

Fig. 3 is a transverse section on the line 33 of Fig. 1.

Fig. 4 is a transverse section on the line 44.- of F 1.

Referring to the drawing, wherein is illustrated the. preferred form of my invention, and in which like numerals of reference indicate corresponding parts throughout the several views, the boiler front A is provided with a suitable opening B for the reception of the burner. Mounted in the opening is a bushing 1 having an annular flange 2. en-

gag cable with the front surface of the boiler front A, and adapted to befastened thereto by a plurality of suitable fastening elements 3 in the form or screws, bolts or the like. The interior of the bushing 1 is screw threaded to receive a supporting ring & having screw threads on its exterior to register with the screw threads of the bushing 1. The supporting ring 4 has interior screw threads and these receive the screw threads formed on one end of an outer discharge pipe 5 The retaining ring 4 is integrally formed with the forward Wall of themixing chamber Wand is therefore, in the form of a flangeenihracing the end of the pipe 5. 13;: will be noted that the mixing chamber 6 is of circular formation, and the outer periphwhich screw threaded to receive the enlerged screw threaded end 9 of an air discharge pipe 1.0 projecting forwardly and through the opening 8, and throu h the centerof the mixing chamber 6. T is air discharge pipe 10 is smaller in diameter than the interior diameter of the pipe 5, and terminates at the end of the jplpe 5, thus pro-' viding an elongated space between the pipe and the pipe 10 which establishes communication. between the interior of the mixingl chamber 6 and the atmosphere.

he enlarged portion 9 carries a flange 11 engageable with the end of the flange 7.

boiler that isbeing heated.

When the enlarged portion 9 .is mounted in position in the annular recess formed in the flange 7, a packing space 12 is provided for the reception of a suitable packing 13 for Incl-dug the joint air-tight. The pipe 10 is extended beyond the enlarged portion to form. the air intake tube L and its end is provided with screw threads for the reception of a cap .15 which receives a circular panel i6 of glass that will be held in contact with the end of the tube 14, when the cap is mounted in place. This glass panel permits the operator to view the interior of the air discharge pipe whereby the condition of the flame at the end of the pipe may be observed. Rotatably mounted upon the tube 1% is a sleeve 17 having a handle 18 attached for the purpose of imparting a rotary movement to thesleo've. The tube 14 is provided with a plurality of suitable apertures, and the sleeve 17 also has a plurality of apertures adapted to be moved into and out of registration with the apertures in the tube. In this manner, the may be regulated as desired.

fine side of the casing or mixing chamber 6 is provided with a projecting port-ion 19 carrying a neck: 20. A. central opening in the i'ieclq is provided. with screw threads for 1 receiving the corresponding screw threads of a fastening head 21 carried at one end of the oil inlet pipe This pipe 22 projects through the central opening in the neck and into the chamber 6 as clearly shown by Fig.

3 of the drawing, and its longitudinal center is preferably disposed at a tangent to the circumferential center line of the space encirclil'ig the pipe 10 in the chamber 6. The opposite end of the pipe 22 projects sufiiciently beyond the head 21 to receive one end of a T-fiti'ing 23 to which is attached a steam in'ta kc pipe 24.

extended centrally through the pipe 22, and also through the center of the T-fitting An elbow 156 is carried by the outer end of the pipe 25, and a suitable cap 27 is mounted upon the screw threaded end of the pipe 25 and extending slightly info the T- litting for 'thepurpose of closing the outer cndof the same. lhe elbow 26 may be connectcd tea suitable source of oil supply, while the pipe 24 will be connected to a. source of steam supply.

In use, the device will be operated either singly or in a series accord'ug to the type of the device in positionon the front of the boiler, the snper-heated steam will be turned on, and the oilthe pipe 25. Of course, the steam will pass through the pipe 22 encircling the oil pi e heat the pipe 25 to a high temperature, thus causing the oil to be ejected from theend of the pipe 25 in an atomizedstate. Furtherair received in the tube An oil intake pipe 25 After mounting and the intense heat of'thcsteam W111 1 non produced in the terior of the. said .mounted inthe other, of said central openottep seen, that with the force applied to the super-heated steam, the action of the device is entirely automatic with respect to the inlnke of both the oil and air. At the end of the pipe 5, the mixture is ignited and a smokeless, sootless and ractically noiseless jet of flame will be proc need that will continue to burn as long as the oil is supplied to the device. The swirling centrifugal momixing chamber is con tinued through the ejecting pipe so that the inflammable spray is under the influence of this swirling movement at the time of igniet of air causes a tubular column produced. formation of carbon at the end of the pipes and a clean burner is thus produced.

lfrom the foregoing it will be observed that a very simple and durable oil burner has been provided, thedetails of which embody the preferred form. 'I desire it to be understood however, that slight changes in the minor details of construction may be madewithout departing from the spirit of the invention or the scope of the claims here unto appended.
